+<h2>Abstract:</h2>
+<blockquote>
+<p>
+As technology scales ever further, device unreliability is creating excessive
+complexity for hardware to maintain the illusion of perfect operation. In this
+paper, we consider whether exposing hardware fault information to software and
+allowing software to control fault recovery simplifies hardware design and helps
+technology scaling.</p>
+
+<p>The combination of emerging applications and emerging many-core architectures
+makes software recovery a viable alternative to hardware-based fault recovery.
+Emerging applications tend to have few I/O and memory side-effects, which limits
+the amount of information that needs checkpointing, and they allow discarding
+individual sub-computations with small qualitative impact. Software recovery can
+harness these properties in ways that hardware recovery cannot.</p>
+
+<p>
+We describe Relax, an architectural framework for software recovery of hardware
+faults. Relax includes three core components: (1) an ISA extension that allows
+software to mark regions of code for software recovery, (2) a hardware
+organization that simplifies reliability considerations and provides energy
+efficiency with hardware recovery support removed, and (3) software support for
+compilers and programmers to utilize the Relax ISA. Applying Relax to counter
+the effects of process variation, our results show a 20% energy efficiency
+improvement for PARSEC applications with only minimal source code changes and
+simpler hardware.
